Problems solved by technology

However, the disadvantages of PPS are: ①The price is too high, which is low in high-temperature-resistant plastics, but it is much higher than general engineering plastics; ②Poor toughness and brittle; ③The viscosity is unstable during processing
Among them, there are many car interiors made of polyphenylene sulfide, so people add various fillers or additives to plastics for modification, but many modification effects are not ideal

Abstract

The invention discloses a method for preparing PPS plastic particles for automotive trim. The method comprises the following steps that all components are weighed according to a weight part ratio and are added into a high-speed mixer to be stirred and mixed; then the evenly mixed materials are added into a double-screw extruder to be molten, plasticized, extruded and pelletized, and then the PPS plastic particles are obtained. The manufactured materials are excellent in mechanical property, heat aging property, photooxidation aging property, precipitation resistance and the like and can meet the requirement for 400h thermo-oxidative aging of polypropylene automotive trim materials; according to the method, the technique is simple.
